pressure relie f valve in the cap when the
engine becomes hot .
.&_ WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
sca lding from hot coolant by following
these steps .
- Turn off the eng ine and a llow it to cool
down.
- Protec t your face, hands and arms from
escap ing fl uid and steam by cover ing
the cap with a large, thick rag.
- Turn the cap slowly and
very carefully
in a counter -clockwise direct ion while
applying light, downward press ure on
the top of the cap.
- To avoid being burned, do not sp ill an-
tifreeze or coolant on the exhaust sys-
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en-
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an -
t ifreeze in its or iginal container and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con-
ta iner clearly marked "poison".
(D Note
- Coolant po llutes the environment and
could cause an engine fire. Excess coo l-
ant will be forced out through the pres-
sure relief
valve in the cap when the en-
gine becomes hot .
- If, in an emergency, only water can be
added, the correct ratio between wate r
and antifreeze~
page 178 must be re-
stored as soon as possib le.
@) For the sake of the environment
Drained coolant should not be reused. Al-
ways dispose of used coolant while obse rv-
ing all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself .
The electric radiator fan is controlled by ther-
moswitches that switch on and off depending
on coolant and eng ine compartment tempera-
tures.
An a uxiliary electric radiator fan* sw itches on
and off depending on coolant temperature
and other vehicle operat ion conditions .
After you switch the engine off, the aux iliary
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switc h
on aga in later by itself
c> &., if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
.&_ WARNING
-
- To reduce the risk of personal injury nev-
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not ru nning.
- The a uxiliary radiator fan sw itches on au-
tomatically when the engine coo lant
reac hes a certain t emperature and will
continue to run until the coolant temper-
ature drop s.
